On a Collection of Mammals from Central and Northern Queensland. 901 



The lower jaw which (more than the other parts of the skull) 

 recalls tliat of the phalaiigers, is comparatively short (as is the 

 Upper jaw). 



Its tooth bearing portion is three times as large, as the distance 

 between the incisor and the premolar. 



Condylus of lower jaw, rather convex, and the glenoidal cavity 

 on the OS temporale tolerably even. 



In the young (A), the skull of which has a length of 83 mm, 

 breadth 49 mm , and length of lower jaw 55 mm, the milk teeth are

still retained. In this the frontal crests are almost indiscernible , in 

 all parts widely separated, and no trace of an elevated central portion 

 of the parietalia between them is present. Interparietale, very large; 

 its height is considerably greater than that of the zygomatic arch. 

 The frontalia are, seen from above, almost equally broad, and as yet 

 show but a slight trace (although visible) of being inflated. The 

 interorbital space is proportionally broader than in the older indi- 

 viduals.
